Abstract (en)

There is provided a driving unit of a welding equipment capable of reducing the size of the driving unit, of reducing the moment of inertia, and of being compact and having an excellent operability. The driving unit of a welding equipment provided with a pressure application shaft (9) that is driven by a motor (1) comprises a screw shaft (7) provided integrally with or substantially integrally with a rotary shaft (5) of the motor (1), a nut (13) provided integrally with or substantially integrally with the pressure application shaft (9) and is screwed with a screw of the screw shaft (7), and a baffling mechanism provided on the pressure application shaft (9), and wherein the rotary shaft (5) of the motor (1) is positioned substantially coaxially with the screw shaft (7) and a rotary force outputted from the rotary shaft (5) of the motor (1) is converted into a reciprocating motion of the pressure application shaft (9).
